Rendering of proposed Digester Facilities from Jerrold Avenue looking West

Built in 1952, the Southeast Treatment Plant (SEP) is located in the Bayview-Hunters Point community and treats 80% of the City's wastewater. After several years of planning and engagement with the community, a plan has been developed to address the long-standing issues of odors and seismic vulnerability, as well as other operational challenges related to the aging solids handling facilities at the SEP.

The proposed Biosolids Digester Facilities Project (BDFP) would replace and relocate the outdated existing solids treatment facilities with more reliable, efficient, and modern technologies and facilities that will help transform the SEP into a modern resource recovery facility, a City destination, a proud neighborhood asset, and an attractive workplace. In addition, the project would locate the digesters farther away from existing residences, make visual improvements in and around the SEP and allow us to meet our Levels of Service goals.

The San Francisco Public Utilities Commission (SFPUC) recently launched the Sewer System Improvement Program (SSIP), a 20-year citywide investment to upgrade our aging sewer system and provide a more reliable, sustainable, and seismically safe system now and for future generations. The SSIP includes a series of facility upgrades at the Southeast Treatment Plant (SEP) located in the Bayview neighborhood of San Francisco.
